PHILIP A. G-EIER, OF QLEVELAN'D, OHIO, ASSIGNOR TO THE P. A. GEIER COMPOF CLEVELAND, OHIO, A CORPORATION OF OHIO.

Specification of Letters Patent.

Patented July 5, 1921.

Application filed July 19, 1916. Serial No. 110,222.

To all whom it may concern Be it known that PHILIP A. Game, a citizen ofthe United States residing at Cleveland, in the county of I yahoga andState'of Ohio, has invented certain new and useful Improvements inDust-Receptacles for Vacuum Cleaning Apparatus, of which .the followingis a specification.

My invention relates to improvements in dust receptacles for vacuumcleamng apparatus, and has for its object the production and that thecollected dust and refuse shall remain, as nearly undisturbed aspossible,

until the contents of the bag have been emptied. Moreover, it isimportant that the flow of air shall be relatively as unimpeded aspossible. On this account certain forms of valves which have been usedhitherto, present the objection that the become filled rearwardly w1ththe accumu ated refuse, and thereby restrict the flow of air whilecausing a constant disturbance of the collected. material, whereby thefiner por tions of the dust are caused to bedriven through the fabric. I

My invention contemplatesthe provision in a fabric receptacle of thisclass, of a partial'diaphragm or partition placed near the entrance tothe bag while affording a passageway above said artition of suchunobstructed area as wil accommodate the dust-laden air at all times.Said diaphragm affords a retaining wall within the bag.

which prevents the return of the accumulated refuse, and at the sametime directs the air currents above such refuse, so that it remainsrelatively undisturbed within the be or receptacle.

he structural features of m invention me. best be explained and unerstood by ma 'ng reference to the accompanying.

drawings, wherein Figure 1 1s a v1ew1n side elevation, partially brokenaway, of 'a'dust receptaclec'onstruoted in accordance with my inventlon.

F g. 2 is across-sectional view on line 2-2, Fig. 1. Fig. 3 1s afragmentary plan view. lug. 4 is another fragmentary vlewillustratlngthe closure means for the open end or top of the bag, andFig. 5 is aview in side elevatlon, partlally broken away, of a vacuumcleaner and associated dust receptacle.

Throughout the several figures of the drawings, I have employed the samecharacter of reference to indicate similar parts.

Referring to F g. ,1, it is seen that the dust receptacle a, WlllOh issuitably constructed of fabric, has an entrance mouth 11' adapted to fitclosely upon the exhaust part or nozzle 6 of a portable vacuum cleaner,such for example, as is shown in Fig. 5. The latter dev1ce, 'as 1s wellknown in the art, usuall provldes a fan for drawing the dirt and re iuse through an inlet nozzle 0, and direct mg t through the outlet nozzle6 into the fabric dust receptacle. Positioned before said nozzle withinthe dust receptacle a, is a partial diaphragm or partitiond which maywell be a fabric member stitched to the bottom and sides of saidreceptacle; leaving, however, a space 0 between the upper wall of thereceptacle and said diaphragm, of an area equal vto or greater than thatof the exhaust nozzle.

In Fig. 1 I have shown by dotted lines, approximately the maximumaccumulation of dust, dirt and other refuse within the receptacle, whichin a portable cleaner ordinarrly is supported at an angle of about 45 inalinement with and by the handle f of the vacuum cleaner. This isaccomplished by a loop or chain f, which is attached to a 011 g, adaptedto he slipped over the open en of the fabric receptac' e for holding thesame tightly closed until such time as-the contents of the receptacleare to be emptied.

The arrows shownv in Fig. 1 are intended to indicate generally, thecourse of the dustladen air currents which are directed over the upperedge of the diaphragmand into the free portion of the fabric receptaclea.

, From this the air escapes through the fabric dle ofthe vacuum cleaner,and also, the bottom of the bag is pouched as shown in Fig. 1 to afforda more spacious container for the refuse.

These, with other features explained, are details of construction, whichare not essential to my invention, except as defined in and by theaccompanying claims.

Having now set forth the preferred embodiment of my invention, 1 claimas new and desire to secure by'Letters Patent, the following 1. In adevice of the class described, the combination with a fabric-Walledreceptacle, having an inlet opening, of a partial diaphragm positionedtherein adjacent to said opening and partitioning the lower ortion ofthe receptacle from side to side, ut afhaving an inlet and an outletopening, of a partial diaphragm intermediate of said openingspartitioning the lower portion of said receptacle from side to side,substantially as set forth.

In testimony whereof I do now aflix my signature in the presence of twowitnesses.
